Wow. That sounds like a rocky road indeed. I don't know you but I can't say I like you saying that you are a loser! Anyone who tries isn't a loser. It is the not trying that is the coward's way.
I don't know near enough of your situation to offer advice, I am more responding so that you know someone hears your pain and you aren't alone.
Since I just stated I don't know enough to offer advice, I will now offer some advice Individual counseling is where I would start.
